After hearing about the European ‘mayo on ff’ thing I decided to try it. Very good; that is pretty much how I like them now. Unfortunately only the really high fat stuff tastes right. Cheese and cheez wiz are usually too much for me. Years ago I spent some time in Lima, Peru, where ff places are as common as pizza places are in the northeast US. The variety of toppings was greater than I’ve seen anywhere…kind of like papas fritas are like pasta or rice in some other countries; they put anything on them, and there are usually several choices of potato. The best I remember was at a little place in the Miraflores section of the city which served a kind of potato that tasted like a yukon gold and was served with fresh strawberries.
